Definitions
- the present invention relates to a novel taxane useful as chemotherapeutic agent, the pharmaceutical compositions containing it and a process for the preparation of 14- ⁇ - hydroxy-1 , 14-carbonate-baccatine III and V derivatives, substituted at the 13 position by an isoserine residue.
- Taxanes are one of the most important classes of anticancer drugs recently developed. The remarkable effectiveness of Paclitaxel and of its analogue Docetaxel in the treatment of several tumors has focused research on substances with antimicrotubular activity. Taxanes are however characterized by a particular action mechanism, in that they promote the assembly of microtubules and inhibit tubuline depolymerization.
- the main drawbacks of the taxanes presently used are: (a) insolubility in water, making mandatory the use of specific carriers which can cause hypersensitization reactions, (b) toxicities which limit dosages, (c) development of resistance mechanisms.
- Cell resistance to taxanes has been related to the MDR phenotype ("multidrug resistance") mediated by the P-glycoprotein transporter, by tubuline alterations, and by changes in the expression of apoptotic regulatory proteins.
- (I) has remarkable cytotoxic and anticancer activities, and is capable of overcoming the resistance of cell lines expressing the MDR phenotype .
- Said compound differs from the derivatives described in the above mentioned American Patent due to the hydroxyl at the 7- position, which in the present case is in alfa configuration. 13- (N-Boc- ⁇ -Isobutylisoserinyl) -14 ⁇ -hydroxy- baccatine III 1 , 14 -carbonate, corresponding to the derivative referred to in US 5,705,508 as SB-T-101131, can be used as starting product for the preparation of compound (I) .
- said baccatine III derivative is either treated with DBU (diazabicyclo [5 , 4 , 0] 7-undecene) in methanol or THF or it is simply left in solution with methylene chloride or chlorinated solvents in the presence of aliphatic alcohols such as methanol, ethanol or propanol with basic allumine for a time ranging from one hour to 14 days.

- triethylchlorosilane is used as silylating agent in step (a), whereas the 1,14 carbonate derivative in step (b) is prepared using phosgene in toluene in a 3:1 methylene chloride/pyridine solution under nitrogen atmosphere.
- step (c) 14 - ⁇ -hydroxy-10 -deacetylbaccatine III or V 7-Tes-l, 14-carbonate is salified with LiHMDS in anhydrous THF, thereby obtaining the 10-hydroxy derivative lithium salt, which is subsequently acetylated with acetyl chloride.
- step (d) The condensation reaction between 14- ⁇ -hydroxy- 7-Tes-l, 14-carbonate-baccatine III or V and (4S, 5R) -N-Boc- 2- (2,4-dimethoxyphenyl) -4 -isobutyl-l-oxazolidine-5- carboxylic acid (step (d) ) is carried out in anhydrous apolar organic solvent, in the presence of a base and a condensing agent such as dicyclohexylcarbodiimide (DCC) .
- DCC dicyclohexylcarbodiimide
- step (e) triethylsilyl is removed with pyridinium fluoride in acetonitrile/pyridine solution under nitrogen, whereas the dimethoxybenzylidene group is removed in methylene chloride solvent by addition of methanol HCl and subsequently of NaHCO .
- Said alternative process (B) comprises the following steps: a') selective acetylation of the hydroxyl at C-10 of
- step (a 1 ) the selective acetylation of step (a 1 ) is carried out with acetic anhydride in the presence of cerium, scandium, ytterbium salts, preferably CeCl 3 .7H 2 0, whereas the remaining steps are carried out as indicated above.
- the present invention also comprises, as intermediate products of the process for the preparation of 14 ⁇ -hydroxy- 1, 14 -carbonate baccatine III or V, the following compounds: 14 ⁇ -hydroxy baccatine III or V, 14 ⁇ -hydroxy baccatine III or V 1,14 carbonate, 14- ⁇ -hydroxy-7-Tes-10- deacetylbaccatine III or V, 14- ⁇ -hydroxy-7-Tes-baccatine III or V, 14- ⁇ -hydroxy-7-Tes-baccatine III or V 1,14- carbonate .

- step (a) leucinol is reacted with Boc -anhydride, and subsequently oxidized to aldehyde in DMS0/CH 2 C1 2 solvent using oxalyl chloride at a temperature below -60°C, neutralizing the formed acid with triethylamine, or oxidizing it with sodium hypochlorite at -2 to -5°C.
- the cyanhydrin of step (c) is prepared by substituting the sulfonic group of the intermediate l-hydroxy-2- (N-Boc) amino-4- methylpentanesulfonate by the cyanide ion.
- step (d) The cyanhydrin is then hydrolyzed to the corresponding carboxylic acid in step (d) by refluxing in concentrated hydrochloric acid.
- step (e) (2R/S , 3S) -3 - (N-Boc) amino-2-hydroxy-5- methylhexanoic acid is converted in the corresponding methyl ester by reaction with diazomethane in ethereal solution.
- step (f ) diastereomer (2R, 3S) is purified by crystallization from cyclohexane or an hexane/toluene mixture.
- Step (g) is carried out in THF in the presence of pyridinium p-toluenesulfonate removing the developed methanol; after completion of the reaction, pyridinium p- toluenesulfonate is neutralized with bicarbonate.
- step (h) the ester is hydrolysed in a methanol/water mixture with potassium carbonate. The reaction mixture is subsequently acidified and the final product is extracted with methylene chloride.

More particularly, the compound can be formulated in the form of tablets, powders, granulates, capsules, injectables, solutions, suppositories, emulsions, dispersions, and the like.
